Secrets of modern communication: mysterious tone mode
Have you ever wondered whydialing the number on your mobile phone, you hear ringing, and at home on the fixed machine - clicks? Or why, when dialing an additional prefix in the support service, they say to us: "Make sure that the phone's tone mode is on"? But what is it and how to activate it?
To begin with, we note that the telephone network is,first of all, an electric circuit, and the tone mode is one of its parameters. At the ATS there is a generator, which generates an electric current, and the telephone apparatus opens and closes this circuit. When you pick up the phone to make a phone call, a current flows into the phone's diaphragm. Then you hear a characteristic beep.
Pulse and tone mode are two ways, withWith the help of which information about which number you dialed can be transmitted to the PBX. When dialing a number in the pulsed mode, you hear clicks. Their number depends on the number you clicked. Therefore, when typing a unit, we hear one click, and when typing zero, we hear ten.
This method of dialing the number you need most oftenIt is used on old automatic telephone exchanges, however the majority of stationary phones are automatically adjusted to it. The main advantage of pulse dialing is considered the possibility of its implementation without modern electronic circuits, and the disadvantages are a long set and the absence of "lattice" and "asterisk" symbols. That is why in the sixties of the last century a tone dialing mode was developed.
This mode assumes the assignment of each digita certain frequency-tone. People with a good musical ear, perhaps, will even be able to determine which figure was dialed when they heard this signal. The tone mode is automatically used in mobile phones, and in fixed phones, it is often necessary to press "star", "Tone" button or select a certain menu option for its connection. Of course, this does not apply to old disk phones. However, transferring the phone to a tone mode still does not guarantee anything, because it is supported only by the most advanced digital or cellular networks.
They are in every major city, so youeasily be able to become their subscriber. If your network supports tone dialing, then you still need to contact your fixed line operator to activate this service, as well as related additional functions. For example, caller ID and blocking of calls from certain subscribers.
Another interesting feature that is available iftone mode is activated, is the ability to hold a call. So you can always answer an important call, and your friends and colleagues will not be annoyed by your constant employment.
Using tone dialing mode, remember that the additional services associated with it are often paid separately and should be supported by your fixed-device model.
In short, today there are two modesDialing: tone and pulse. The tone mode is more modern and is used by default in mobile phones, which allows their owners to use a number of functions of modern networks. In addition, he has no shortcomings in the "old" impulse set.
